MIPS: Malta: Setup RAM regions via DT
Move memory configuration to be performed via device tree for the Malta board. This moves more Malta specific code to malta-dtshim.c, leaving the rest of the mti-malta code a little more board-agnostic. This will be useful to share more code between boards, with the device tree providing the board specifics as intended. Since we can't rely upon Malta boards running a bootloader capable of handling devictrees & filling in the required information, a piece of shim code (malta_dt_shim) is added to consume the (e)memsize variables provided as part of the bootloader environment (or on the kernel command line) then generate the DT memory node using the provided values.
